Simulation and Experiment Research on the Shape Coefficient of Multi-bundled Conductors for Overhead Transmission Line

文章采用风洞试验和数值模拟的方法,对多分裂导线风荷载体型系数变化规律进行了分析。根据试验和仿真结果,分析了风速、分裂间距、外径、风攻角、风向角对多分裂导线风荷载体型系数的影响,得出多分裂导线风荷载体型系数小于规程规定的结论,总结了多分裂导线风荷载体型系数随各种因素变化的规律。

In this paper,it analysis the effect of the shape coefficient of multi-bundled conductors.According to the result of the wind tunnel test and numerical simulation,the paper analysis the effect of wind speed,split spacing,outside diameter of conductor,wind attack angle and wind direction to shape coefficient of multi-bundled conductors.Then,the paper propose that the shape coefficient of multi-bundled conductors is smaller than that is given by the standard actully.it is necessary to take notice of the value of shape coefficient of multi-bundled conductors.
